I fixed it by simply placing a value on my own time. When I started I figured my time was worth at least $50/hr. Spending an hour trying to save less than $50 is an absolute loss, recognizing that, my behavior changed easily.
Paradoxically, this works less and less the higher your income is.
If you value your time at, say $200/hr and you work with other people who claim their billable labor is also close to $200/hr, and you value it at $15/hr, then, no, you’re going to do it yourself.
At high income it can make you feel silly for doing anything other than working. You second-guess walking the dog even if you enjoy it because you can pay someone to do it for so much less.
